Design and Off-Design Performance Analysis of Ocean Thermal Difference Power Plant Turbines,

摘要

A procedure has been developed to determine the axial-flow turbine design that operates at the maximum attainable efficiency for the design specific speed. The procedure uses the results of Balje's optimization study and accounts for the Reynolds number variation of Balje's optimized parameters. The procedure has been used to study the variation of the design parameters of ammonia and propane OTDM turbines. A procedure has been developed to predict the off-design performance of turbines designed by the previously mentioned design procedure. The inlet state,mass flow and rotational speed have been varied to produce performance maps for a series of ammonia and propane OTDM turbines.
